我如何在asp.net应用程序的应用程序中添加图形 [英] how can i add a graphs in our application in asp.net application

问题描述

我想使用c#在asp.net中创建折线图，因此在x轴上将显示时间，在y轴上将显示货币.出价和要价两个值将在图中的红色和蓝色两行显示.该图从数据库中获取值，并每秒更新一次，因此该图应该是连续的.

i want to create a line graph in asp.net using c# so in x-axis it will show the time, in y-axis it show the currency. two values bid and ask are to be shown by the two line red and blue in the graph. the graph takes the values from database and also update itself after every second so that the graph should be continuous. how is it possible?

推荐答案

最明显的方法之一是将Microsoft Chart Control用于ASP.NET:
http://www.microsoft.com/en-us/download/details.aspx? id = 14422 [^ ]，
http://www.asp.net/community/control-gallery/Item.aspx? i = 3110 [ ^ ]，
http://www.asp.net/web-forms/videos/net-4/chart/aspnet-4-quick-hit-chart-control [

One of the most apparent ways is using Microsoft Chart Control for ASP.NET:
http://www.microsoft.com/en-us/download/details.aspx?id=14422[^],
http://www.asp.net/community/control-gallery/Item.aspx?i=3110[^],
